Receiver operating characteristic curves of urinary presepsin/creatinine, urinary presepsin, and NAG/creatinine levels for tubulointerstitial nephritis diagnosis. The P value was calculated using DeLong’s test. P value adjustment was calculated using the Bonferroni method. aP < 0.001, vs. NAG/creatinine. NAG, N-acetyl-β-D-glucosaminidase; AUC, area under the curve.
